Likely causes
Underwatering
Most likelyHow to tell: The soil feels dry to the touch, and the leaves look limp or wilted. The plant usually perks up within a few hours of watering.
What to do: Give the plant a deep soak until the water drains through the soil. Maintain a schedule of watering every 7 to 14 days depending on the heat.
Sclerotinia stem rot
PossibleHow to tell: The plant wilts suddenly, and you see a white, cottony mold near the base of the stem. The stem may eventually turn soft and mushy.
What to do: Remove and destroy the entire infected plant to prevent the fungus from staying in the soil. Do not compost the infected material.

When to worry
If the plant wilts even when the soil is moist, it is likely a stem rot issue. This is serious and requires removing the plant.
Stopping it coming back
